Aion Business Rules Expert has an ImageList datatype where the defined columns can be changed at runtime. This document will show how this can be achieved.
The Imagelist column order can be easily rearranged. When developing the application, in the ImageList properties, go to the "Extended Style" tab. The option "Header Drag and Drop" can be selected. Once this is selected, imagelist columns can be dragged to any valid position in the imagelist itself.
